Heidi’s wardrobe, um, malfunction; Piven wins

Thank heavens Denny Crane, alias William Shatner, came onstage and added sparkle to a dull beginning by the five reality hosts of the evening, who said they had nothing prepared.

And their entrance was just that: nothing. Luckily Shatner was called up on stage to critique Klum’s modest tuxedo outfit, found a stray string, and, bada bing — she was suddenly in a hot pants stunner that showed off her sensational bod.

Jeremy Piven of “”Entourage” nabbed the first Emmy for best supporting — comedy.
